The primary goal of this interventional study is to objectively examine the prevalence of walking-related performance fatigability, together with the psychometric properties of its measuring parameters. The secondary aim is to investigate the relation of other clinical symptoms to walking-related performance fatigability.
The following three research questions will be addressed:
1. How prevalent is walking-related performance fatigability and what are the psychometric properties of fatigability formulas in preparation of use as experimental outcome measure?
2. What are associated symptoms of walking-related motor fatigability and how long does this manifest?
3. What is the relationship between cognitive fatigability and walking-related performance fatigability?
participants perform two six-minute walking test (6MWT), with 3-5 days in between. Before and after the 6MWT, three screenings test (spasticity, muscle strength, balance) are executed and the participants have to indicate the severity of eleven possible symptoms (= symptom inventory, SI) on a VAS scale. These screening tests and SI are continued every 10 minutes for half an hour. During a third test session, participants perform a 6-minute vigilance alphabet test in rest and while doing a 6MWT to investigate the relationship between cognitive and motor fatigability.
